ROLLER COPYING-PRESS.

SPECIFICATION forming part of Letters Patent N o. 663,051, dated December 4, 1900. Application tiled November 20, 1899. Serial No. 737,605. kllo modem T0 cti/whom t may concern.-

Be it known that we, FRED W. TOBEY, re-

siding at Cincinnati, and ALEXANDER DOM,

residing at Hartwell, in the county of Hamilton and State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Roller Copying-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciication.

Our invention relates to that class of roller copying-presses in which the paper from a continuous roll is automatically moistened on its way to a pair of pressure-rolls, between which it is fed with the type-written or manuscript copy and by means of which thev impression is made upon the moistened paper, so as to form a perfectly-legible copy; and it has for its object the improved construction of such presses whereby their compactness, efficiency of action, and durability are greatly increased and whereby the pressure, tension, and adjustability can be readily elfected.

The novelty of our invention will be hereinafter set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure l, Sheet l, is a side elevation of a press embodying ou'r invention and mounted upon a cabinet in readiness for use. Fig. 2, Sheet l, is a central sectional side elevation of the press. Fig. 3, Sheet 2, is a sectional side elevation of the right-hand end of Fig. 2. Fig. 1l, Sheet 2, is a diminished side elevation of the press, with the casing that carries the press-rolls, damping-roll,and actuating mechanism raised on its hinges at right angles to the base.

The same letters of reference are used to indicate identical parts in all the figures.

A is any suitable base, in this instance, as seen in Fig. l, mounted on a table or cabinet B. Supported upon this base A and hinged thereto at one end, as at a, is a case C, cornposed in this instance of two side walls c, held together and -in an upright position by the cross tie-rods d ef, Fig. 2, the latter serving as a holder fora latch g, pivoted, as at YL, to the base and by means of which the case can be locked to the base, or by throwing back the latch it can be lifted bodily on the hinges a, as seen in Fig. 4, at right angles to the base.

Journaled on suitable blocks or bearings t' on the base is a shaftj or trunnions projecting from the center of a roll of copying-paper lo. ,Also carried on suitable supports Z on the hase, near the hinging end of the case, isa water-pan D, whose end farthest from the roll lc is preferably rounded, as shown.

In each upright c of the case is a vertical guideway, the upper part m of which is wider than the lower part n, and these guideways are directly opposite each other and about in line with the center of the pan D.

Fitted in each of the ways n is a sliding block o, in which is journaled the shaft or trunnions of a wetting-roll E, in this instance having a core around which is secured any suitable substance to hold water-such as cotton, linen, or other absorbent fabric p-and the lower part of the roll is submerged in the water of the pan D, as seen in Fig. 2. Setscrews q, having suitable bearings r, Fig. 3, in the uprights c of the casing bear against the under sides of the bearing-blocks 0 and serve to adj ust the saine vertically. Confined in the ways m are two other sets of sliding journal-blocks s and t, in which are journaled comparatively hard rubber rolls F G in contact with each other and the latter in contact with the top of the roll E. Coiled springs u are interposed between the blocks` s t, and similar springs fw are interposed between the blocks s and o. Bail-arms H, Fig. 2, connected by a bail or handle I, have on their inner ends cams J, engaging the blocks t and pivoted, as at b, to the headpieces K, covering the ways m and secured to the uprights c of the frame, the construction being such that when the handle I is thrown forward to the position shown in Fig. 2 the cams exert their greatest pressure upon the blocks t to force the rollers F and Gr together with the maximum pressure, while by turning the handle in the opposite direction the pressure or tension between the rollers is lessened and can be regulated as desired to suit the requirements of the work to be done. It will be notioed that when the maximum pressure is eX- erted on the blocks t the blocks s rest on the bottom of the ways m, 'which serve as stops,

IOO

and therefore the pressure exerted by the cams is not transmitted to the roller E, and that the pressure of the latter against the roller G is effected and regulated bythe set of screws q.

A feeding-plate L for the matter to be copied rests upon the rods d c in line with the meeting-point of the rollers F G, as seen in Fig.A 2, and, if desired, baskets M N may be removably attached to the case on each end, as seen in Fig. l.

The paper from the roll K is first passed under the pan D and thence up between the rollers E and G, thelatter supplying sufficient water to the paper to give it the proper degree of moisture. The paper is thence drawn between the rollers F G and is passed over a carrying-off or tumbler roll O, journaled between the sides of the case and having radial blades `In its passage the paper to be copied is fed, with the writing face down, simultaneously with the moistened copyingpaper between'the rollers F G, and the copying is thus effected in a way well known in this class 0f machines. The copied sheets may pass into the basket N, while the continuous paper from the roll K may pass over the roller O and down into the cabinet B, where it is wound upon a reel P, (shown by dotted lines,- Fig. 1,) or any other disposition of it that is desired may be made.

For operating the mechanism the roller G is provided with a crank-handle Q, and a flexible or coiled-spring belt u is connected from a grooved pulley on the shaft of the roller G to a similar pulley on the shaft of the roller O. A similar belt may extend from a pulley on the opposite outside end of the shaft of the roller G to a pulley on the shaft of the reel P, so that all of the parts receive simultaneous rotation by the turning of the handle By supporting the roll of paper K and the water-pan upon the base A the case can be raised at any time to get at these parts, which remain stationary on the base, as seen in Fig. 4.

Of course it is to be understood that whenever the machine is not in actual use the cams J are thrown back to release the pressure on the blocks if, and consequently7 on the subjacent blocks, whereupon the springs u w slightly separate the rollers to prevent any flattening of the same at the points of contact, as will be readily understood.

Having thus fully described our invention, we claim-- 1. In a roller copying-press, the combination of a bottom wetting-roll, a pan of water in which said roll is partly submerged and two superimposed copying-rolls, the lower one of which is in contact with the wetting-roll, means for regulating the pressure between the two upper rolls, means for automatically separating all of the rolls when the pressure on the uppermost roll is released, and independent means for regulating the pressure of the lower roll against the middle roll, whereby the paper passed between the wetting-roll and the middle roll is wet and then subjected to pressure to wring out the excess of moisture and finally passes between the two upper rolls in contact with the paper tobe copied, substantially as described.

2. In a roller copying-press, the combination of a base, a roll of copying-paper supported and journaled upon sai'd base, a waterreceptacle likewise supported upon said base with an opening under it for the passage of the paper from the roll, a case resting upon said base and hinged thereto at one end, three rolls journaled in said case in vertically-sliding journals, the lowermost roll being provided wit-h an absorbent surface and partiallyT submerged in the water-receptacle, the middle roll having bearing contact with the lower roll and the top roll, springs normally tending to separate the three rolls, and means for imparting pressure to all of the rolls at their contact-points in varying degrees of tension, whereby the copying-paper is first passed under the water-receptacle, thence between the lower roll and the middle roll where it is wet and the excess moisture pressed out, and finally passed with the written matter to be copied between the two upper rolls, substantially as described.

3. In a roller copying-press, the combination of a water-receptacle, a bottomwettingroll in sliding journal-boxes said roll being partly submerged in the water of the receptacle, two superimposed rolls in sliding journal-boxes of greater width than that of the lower roll, springs interposed between said journal-boxes, set-screws for the lower journal-boxes, and cam mechanism for the upper jou rnal-boxes, substantially as and for the purpose specified.

4. In a roller copying-press, the combination of the base A, the paper-roll 7o and water-pan D, the case C hinged at one end to the base A and latched to it at the other end, the wetting-roll E adjustably journaled in the case C, and the wringing and copying rolls F G adjustably mounted above the roll E, the carrying-off roll O jowrnaled in the case C, and the cams J for exerting pressure upon the top most roll F, substantiallyas described.
